bugfix: Process escaped colon in GCC depfiles.  (#1774)

* Added ability to parse escaped colons in GCC Dep files enabling ninja to parse dep files of GCC 10 on Windows

* Added generated depfile_parser.cc

* Addressed formatting

* Added extra tests with real world examples of paths produced by both GCC 10 and Clang and GCC pre 10. Adjusted one test so it doesn't fail

* Adjusted regular expression to not match \: if the character following the : is either EOF or whitespace

* Fixed typo in regex (should be 0x20 for space not 0xa)

* Changed regular expression form using lookahead to instead matching a separate expression. This was needed as re2c pre version 1.17 is broken when using lookaheads. Also added tests for \: followed by whitespace

* Addressed formatting

* Forgot a missing std::

* Fixed formatting for spaces after , as well as respecting column width

Ninja

Ninja is a small build system with a focus on speed. https://ninja-build.org/

See the manual or doc/manual.asciidoc included in the distribution for background and more details.

Binaries for Linux, Mac, and Windows are available at GitHub. Run ./ninja -h for Ninja help.

Installation is not necessary because the only required file is the resulting ninja binary. However, to enable features like Bash completion and Emacs and Vim editing modes, some files in misc/ must be copied to appropriate locations.

If you're interested in making changes to Ninja, read CONTRIBUTING.md first.

Building Ninja itself

You can either build Ninja via the custom generator script written in Python or via CMake. For more details see the wiki.

Python

./configure.py --bootstrap

This will generate the ninja binary and a build.ninja file you can now use to build Ninja with itself.

CMake

cmake -Bbuild-cmake -H.
cmake --build build-cmake

The ninja binary will now be inside the build-cmake directory (you can choose any other name you like).

To run the unit tests:

./build-cmake/ninja_test
